踩过的坑：
坑1
ActiveMq断网之后不会自动重连，需要将连接字符串修改为：failover:(tcp://192.168.0.47:61616)?randomize=false
如果有多个地址可以使用 逗号分隔，例如：failover:(tcp://192.168.0.47:61616,tcp://192.168.0.48:61616)?randomize=false
坑2
ActiveMq 分为 持久化、非持久化
持久化： 程序关闭之后服务器发送消息会存在在消息队列中，再次上线后会将之前消息全部再次接收，
非持久化：程序关闭后，再次上线后这段时间不会接收到历史消息，等于是从新开始
开撸
private void CreateMq() { ActiveMqManager mq = new ActiveMqManager(); mq.Listener += MqListener; mq.CreateTopic("termNotifyTopic"); } private void MqListener(string message) { Console.WriteLine(message); }
